LAMP.

SPECIFICATION forming part of Letters Patent No. 266,637, dated October31, 1882,

Application filed April 6, 1882.

To all whom it may concern 7 Be it known that 1, ANDREW NELSON, acitizen of the United States, residing at Bushl'ord, in the county ofFillmore and State of Minnesota, have invented certain new and usefulImprovements in Lamps; and I do hereby declare the following to be alull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters or figures of reference marked thereon, which form a part ofthis specification.

My invention relates to an improved hanging lamp in which the body oroil-containing reservoir is movable, and is provided with two or moreburners, above which is mounted a reflector provided with smokeways andcaps to allow the gases and smoke .to escape upward without defacing thereflector or theceiling above. The oil-reservoir is preferablyrectangular in cross-section and elongated, and is held in aclamping-scat which fits snugly to the bottom of the reservoir, and hassufflcient elasticity, which is exerted inward at the top against thesides of the reservoir to hold said reservoir securely in place, butwhich yields enough on occasion to allow the reservoir to be withdrawnendwise, or even lifted up if sufflcient force is applied. Theclamping-seat is united with the reflector-top by metallic rigid straps.The whole device is suspended from the ceiling by a chain which isattached to the reflector by a hook, and is passed over a pulley securedto the ceiling. At the other end of the chain a balance-weight issecured.

The accompanying drawings form a part of this specification andillustrate theinvention.

Figure l is a side elevation of the device. Fig. 2 is a transversecentral section. Fig. 3 is a section showing how the end of thelampreservoir is held. Fig. at is an end elevation of the reservoir andseat, showing the inward tension of the sides of the seat.

Similar letters of reference indicate corresponding parts in all thefigures. Y

A is the suspending chain or cord. It is attached to the reflectorB atthelower end, and passes through an opening in the weight A and over apulley, A at the upper end, and then down, and is fastened to theweight. The

(No model.)

pulley A is secured to the ceiling. The weight A about balances theweight of the suspended lamp, so that by pulling the lamp down orpressing it up the weight will move one way or another and hold the lampat rest at any height.

The reflector B is shown rectangular in shape, concave below, withcrimps or angles extending from each corner to the center. The form ofthe reflector may be varied. It may be oval. Its under surface may beconcave without the angles, and corrugated, if desired. 1t may besurfaced with any burnished or reflective material. Smokeways b areprovided at suitable points in the reflector above the burners in thelamp, and are covered with caps B, which are mounted on short legs 1)above the ways. These smokeways allow the gases and smoke to passthrough them, instead of lodging upon and destroying the reflectivequality and brilliancy of the reflector. The caps above the waysintercept the discharge of smoke and gases and prevent their rising andlodging upon the ceiling above. Straps 0, attached to the reflector,reach down andhave secured to their lower ends the clamping-seat 1).These straps O are inflexible and rigid. They m ay be attached eitherrem ovahly or securely by solder to the reflector and clamping-seat.Their length in great measure determines the distance which the lampwill sit from the reflector. This distance is suflicient to accommodatethe chimneys of the lamp, and may be varied according to therequirements of the case.

The clamping-seat D has sides D, which have a springiness or elasticityexerted inward against the body of the contained reservoir. This seat isshown as made of sheet metal, and is preferably constructed of thismaterial; but it may be made of wire or strap metal suitably united toform asecure bottom and elastic sides. The elasticity of these sides I)is supplemented by the action of the straps O, which are rigid andproperly attached to press the sides inward. The seat is open-ended andreceives the reservoir E between its sides. The reservoir E isrectangular in section, and is provided with two or more burners, 0. Anopening, 0, provided with a screw-stopper, allows filling withoutdisturbing the burners or removing the reservoir. The reservoir is madethe reflector above, so that a mellow, even light is thrown over allbeneath it.

This lamp is particularly designed for use in billiard-rooms over thetables, and the effectual reflection and thorough distribution of therays, coupled with the very. meager chance for shadows, make itpeculiarly useful in thissituation. The lamp, as is clearly apparent, isadmirably adapted for use in any situation where a hanging lampordrop-lightcan be used.

As stated, the form of the reflector may be varied within widelimitswithout departing from the spirit of'the invention, and thesuspending-rod may be variously formed and attached to the reflector. Asshown, the way of attachment is very simple. A hook, to, is provided onthe top of the reflector, and the cord or chain A is hooked or loopedtherein. The weight A moves easily over the suspending means A, and avery etlicientelevating or lowering means is provided.

It is practicable to attach ways on the side of the reservoir for theclamping-edges of the sides of the seat to spring into, and thus securea firmer hold, although the pressure of the elastic sides upon a planesurl'ace is usually sufficient to hold the reservoir under anycircumstances accidentally occurring.

' The body of the receptacle is formed of a single piece of metal bentover and lapped on the bottom. The ends are drawn and inserted into thisrectangular body and soldered or otherwise secured.

Having thus described my invention, whatI desire to claim and secure byLetters Patent 1s 1. In a hanging lamp, the combination of therectangular-shaped reservoir E, slid into the seat, with the suspendedlamp-seat D, having the inwardly-sloping elastic sides D pressingagainst the sides of the reservoir E, as set forth.

2. In a hanging lamp, the combination of the reservoir E andclamping-seat D D with the rigid straps U, secured to the reflectorabove and adding to the inward spring of the sides D below, as setforth.

3. In a hanging lamp, the clamping-seat D D, formed in one piece ofmetal, the sides D being bent up and inward to press against thecontained reservoir when in place.

In testimony whereof I affix my signature in presence of two witnesses.

ANDREW NELSON.
